Means for combining individual light beams of different wavelengths to a coaxial light beam

Device (1) for combining individual light beams (7, 8, 9, 10) to a coaxial light beam (12), comprising - a device body (2) having a plurality Einkoppelpositionen (3, 4, 5, 6) for the light beams (7, 8, 9, 10) and a coupling-out (11) for the light bundle (12), wherein the light wavelengths of the light beam (7 , 8, 9, 10) to the light beam (7, 8, 9, 10) differ, - dichroic mirrors (15, 17, 19, 21) each reflective to the light wavelength of the incoupled light beam (7, 8, 9, 10) and transparent to the light wavelengths of the other light beams (7, 8, 9, 10), and the inside of the apparatus main body (2) are arranged consecutively in the direction of the light beam (12), and - adjusting means (14, 16, 18, 20) for coaxial alignment of the individual light beams (7, 8, 9, 10) relative to the beam direction of the light beam (12), each of the dichroic mirrors (15, 17, 19, 21) with a hinge for influencing the direction of ...
